Abstract

The electron-phonon induced attenuation of optical phonons, arising in impure metals and superconductors under laser irradiation, is investigated. The electron-phonon interaction is considered in the frame of reference moving together with the lattice. The screening of the longitudinal and transverse electromagnetic fields is taken into consideration for various values of the electron mean free path l, the optical phonon frequency ω0, and wave vector q. .AE
